4 Claims. 1

The invention relates to an improvement in inkstands and especiallythose of the combination type in which a container, or bottle,containing ink is combined with the inkstand.

Among the objects of the invention is to provide a construction whichwill prevent leakage in case the inkstand is overturned; also aconstruction that will materially lessen evaporation of the ink.

The construction of the inkstand is also such as to embody various newconstituent features, all of which can best be seen and understood byreference to the drawings, in which-- Fig. 1 is a front elevation of theinkstand.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a top plan of the inkstand with the ink container, or bottle,and its cover removed.

Fig. 4 is a cross section of a detail of construction to which specialreference will later be made; and

Fig. 5 is a section on the line 55 of Fig. 1.

Referring to the drawings: i represents the base of the stand,preferably a hollow base. The base is preferably made generallyrectangular at the back, and brought forward to present a rounding front1'.

Supported from the base is an enclosure 2, generally rectangular inform, with side walls 3, 4, "5 and 6, and a bottom I. Formed Within andby this enclosure is a reservoir 8 filled from a container, or bottle 9,containing ink, which occupies an inverted position within the inkstand, and is supported as will later be explained.

Located within the enclosure 2 is a partition or diaphragm l havinupstanding flanges H which make closed connection all around with theinside surfaces of the side walls 3, 4, and 6 of the enclosure. Thepartition has a depressed portion H (see Fig. 2) having a bottom I3within which is an opening I4. The bottom of the depressed portion ofthe partition and the opening within it occupy a vertically spacedrelation to the bottom I of the enclosure forming the reservoir.

The ink container or bottle is preferably one provided with the cap l5having threaded connection with the neck l6 of the container, and thiscap, when the container is occupyin an inverted position in theinkstand, is located within the depressed portion i2 of the partition.The cap has an opening ii in it. This opening is controlled by a valvel8 which prevents the escape of ink through the opening in the cap whenthe container is being held in an inverted position for placing itwithin the inkstand.

2 During this operation the valve on the cap will pass through theopening in the bottom l3 of the depressed portion of the partition andengage the bottom I of the enclosure, and thereupon the valve will beopened and ink will issue from the container to fill the reservoir.

When the cap I5 to the container 9 is located within the depressedportion of the partition 9. portion of the surface of the cap around theopening H in it will occupy a circumscribing relation to the opening Min the bottom l3. A compressible seal forming annular washer I9 isinterposed between said cap, and the bottom l3 of the partition aroundthe opening [4 therein. The washer is preferably cemented to the bottoml3 of the depressed portion of the partition. A seal will accordingly beformed between the opening I! in the cap andthe partition around theopening It in it, upon the application of pressure to the container forcompressing the washer, and ink issuing from the container will thenpass only into the reservoir. Pressure is applied to the container forcompressing the washer, and forming the seal, in the following manner.

Mounted upon the enclosure 2 is a cover 20 which is detachably securedto the enclosure, the enclosure and the cap co-operating to form ahousing for the ink container, or bottle.

Interposed in a space left between the top end of the invertedcontainer, or bottle, and the adjacent top end of the cap is a pad 2| ofsome flexible elastic material which will become compressed when thecover is attached to the enclosure. The pressure of the compressed padagainst the container acts through it to compress the washer !9 and formthe seal between the end of the container and the partition around therespective openings therein.

The cover, and, for that matter, the entire stand, apart from the inkcontainer, or bottle, is made of plastic material which in itself has acertain amount of elasticity when in a thin plate, as in the cover, andaccordingly may be deformed slightly by pressure, and returned to itsnormal shape when the pressure is removed. The bottom end of the coverfits within the top of the enveloping walls of the enclosure, andpreferably in bearing engagement with the top edge to the flanges ll ofthe partition or diaphragm I 0. The opposite fore and aft sides of thecover along their bottom edges are provided with clips 22 which, whenthe cover is distorted by pressure, are brought into position to entersockets 23 formed in the top edges of the adjacent walls 3 and 6 of theenclosure so that when the deforming pressure upon the cover is removedthese clips will enter the adjacent sockets and the cover will beattached to the enclosure, its detachment being obtained by againdeforming, and releasing the clips from their sockets, whereupon thecover may be removed.

The ink reservoir 8 lies between the bottom 'I of the enclosure 2 andthe bottom [3 of the partition or diaphragm. The bottom I of theenclosure is provided with a cutout by which ink in the reservoir mayenter and lie contained within an underlying dipwell 25. This dipwellhas a bottom 26 and sides 21 which lie in closed connection with theedges of the cutout in the bottom of the enclosure. The bottom and sidewalls of the dipwell extend forward beyond the fore end wall 6 of theenclosure 2 and connect "with a hollow upward extension 28. Thisextension passes upwardly by the front end wall 6 or the enclosure,making closed connection therewith and lies contained within a moldedfront '29 of the inkstand which extends fromtheround- =ed front l of itsbase portion and merges H with the front of the enclosure 2'. Thismolded front has an upwardly rounded central portion 30 with an opening3| in it and the top edges of the upward extension 28 of the dipwellmake closed connection all around with the edges of this opening. Theopening is closed by a plate 32 bearing a pen receiver or holder 33whichextends downwardly into the upwardextension 28 and through whichentry is had to the dipwell.

Ink will rise in the ink reservoir and dipwell only to a pointsubstantially level with the opening M in the bottom of the partition,for when the reservoir 8 has been filled to a point where the opening [4in the bottom of the partition has become closed by the ink, then aircan no longer enter the container, and ink cannot issue therefrom untilthe level of the ink in the reservoir has become lowered to permit-oithe entrance of further air through the opening in the bottom of thepartition.

With an inkstand as thus constructedn-o ink can escape from "theinkstand if turned overupon its side or upon its back. Evaporation-ofink will be reduced to a minimum -for the only opportunity afforded forevaporation is by way of the entrance to the dipwell, and this entranceis usually closed when the inkstandis not innse, by leaving the pen inthe receiver or holder 1.
